Abstract

Procédé de fabrication d'un papier chargé, consistant à traiter séparément, en milieu aqueux, les fibres avec un polymère chargé et la charge avec un polymère chargé de meme polarité, puis les fibres ou la charge avec un polymère chargé de polarité opposée, à mélanger les deux suspensions obtenues et à drainer la pate pour former une feuille de papier chargé. Le polymère chargé peut etre choisi entre autres parmi les polyacrylamides et les copolymères amine-amide-épichlorhydrine cationiques et les amidons anioniques et cationiques.Process for manufacturing a loaded paper, consisting in treating separately, in an aqueous medium, the fibers with a charged polymer and the filler with a charged polymer of the same polarity, then the fibers or the filler with a charged polymer of opposite polarity, mix the two suspensions obtained and drain the dough to form a sheet of loaded paper. The charged polymer can be chosen among others from polyacrylamides and cationic amine-amide-epichlorohydrin copolymers and anionic and cationic starches.
